Lexmark T420d Monochrome Laser Printer - Humble Office Worker

All is left is to evaluate indirect features of the printer, such as, the pleasure of contemplating its body, the quality and functionality of the trays, as well as the thickness of the power cable. Last half of the previous sentence is, of course, a joke, but everything else is quite true. More than half of their "weight" in the testing of modern laser printers own to the additional functionality.

Fortunately, Lexmark T420d has no problems with additional functions, as well as with everything else.

First, pay attention to the print speed. 21 pages per minute is enough for virtually any small or even not so small offices. The declared first page out time looks impressive, too. The 272 megabytes of memory, which may be installed in this printer, are huge, but the most important highlight of this printer is that even the most basic version includes automatic two-sided printing unit. In general, there is little remarkable in the unit itself, but its usefulness is difficult to overestimate, and it usually costs pretty money. So its presence in not very expensive devices with very decent performance is impossible to remain unnoticed.

In the basic configuration, the input capacity is not very large, but with additional trays it can be increased up to 850 sheets. Lexmark T420d is able to print up to 50,000 pages per month, and has a cartridge with a fairly large supply of toner. This, of course, is benefit, as you'd have to replace it less often. Standard USB and LPT ports can optionally be enhanced with internal print server. Notable are the very low noise and the small dimensions, among other characteristics of the printer.

The exterior of the printer a very much conventional: a box like many others. Feeder for A4 sheets is located at the bottom, non-standard media is loaded from the front; the output is collected in top of the device. For printers in this class, such design is rather standard. The printer only has two buttons, 'Continue' and 'Cancel', with self-evident functions. There are 6 LED indicators: 'Ready/Data', 'Low toner', 'Load/Remove paper', 'Paper Jam', 'Error', 'Press continue', and their purpose, too, needs no explanation.

Included are several types of drivers: only PCL, only PS, and PCL and PS together. All of them are installed and work seamlessly. Their functionality is good, too -- all that should be configured, is configured. By the way, range of potential users of the Lexmark T420d is not limited to fans of Windows OS - there are drivers for even such exotic operating systems like UNIX AIX.

First page really comes out from the printer in, well, maybe not ten, but 11 seconds. Printing speed at 5% pages coverage differs from the declared, but not a lot, just in one page. The printer is able to produce 20 pages per minute at 600 dpi resolution. In two-sided printing mode, Lexmark T420d can deliver up to 7 full-color pages per minute. The duplexing unit works smoothly as it should, no clicks or strokes.

Saying something meaningful about the printing quality and supporting it with super tests and analysis using super instruments is extremely difficult. Everything on the page is beautifully visible; the radial rays converge almost in the center. Even at resolution of 300 dpi and the lowest density of toner, the quality of printing is still very decent. The difference between the 300 dpi and 600 dpi modes is visible, but the 1200 dpi with IQ Technology and 600 dpi modes look almost the same.

It does smell ozone (and quite significantly) when printing, but there is no noise during work. Well, actually there is some, but not so much, and definitely less than from other printers in this class. Normal paper is served without any problems, we never managed to get the printer to jam it. However, it's not the case with rumply paper: it remains in the printer, and you'd have to give it some effort to get it. Thick paper is no problem, the printer swallowed it without issues.
